i guess, you should add the new value in postgresql.conf too.
just a question, why not add a flush value and make it behave like on?
actually sync rep is on in both cases and having the different names
makes more easy to unserstand what is happening.
i only want to keep on for compatibility but i wouldn't mind if we
remove it in favor of more descriptive names.
or there's any difference between on and flush that i'm failing to see?
